[0014]
The GPS positioning unit 3 calculates the latitude and longitude of the current position from the received radio wave, outputs latitude / longitude data indicating the latitude and longitude, and supplies the latitude / longitude data to the time generation unit 4 and the first recording unit 5. At this time, the GPS positioning unit 3 outputs latitude / longitude data every predetermined time, for example, every 30 seconds.
[0015]
When the latitude / longitude data is supplied from the GPS positioning unit 3, the time generation unit 4 supplies time data indicating the supplied time to the recording unit 5.
[0016]
The recording unit 5 has a detachable first recording medium, records the latitude / longitude data from the GPS positioning unit 3 on the first recording medium, and the latitude / longitude data is measured from the time generation unit 4. The time data which is the new time is also recorded on the first recording medium.
[0017]
An example of trajectory data composed of latitude / longitude data and time information recorded on the first recording medium by the trajectory recording apparatus 1 having such a configuration is shown in FIG.
[0018]
For example, at time “07:15:00”, latitude “N (north latitude): 34 degrees 33 minutes 24 seconds” longitude “E (east longitude): 139 degrees 10 minutes 13 seconds”. Similarly, there is latitude / longitude data indicating the latitude and longitude at the time “07:15:30”, “07:16:00”,..., Every 30 seconds.
[0019]
Here, the position at time “07:15:00” is point A, the position at time “07:15:30” is point B, and the positions every 30 seconds are point C, point D, and point E. In this case, the trajectory data is a plot of the trajectory actually moved by the user as shown in FIG.
[0020]
FIG. 4 shows the image / sound recording apparatus 10.
[0021]
The image / audio recording apparatus 10 includes a camera unit 11 that captures a subject, a microphone unit 12 to which external audio is input, a time generation unit 13 that generates time information, and a second recording unit 14.
[0022]
The camera unit 11 generates image data of the subject in synchronization with the user's shutter operation, and supplies the image data to the second recording unit 14. The microphone unit 12 converts voice into voice data by a user's voice input operation and supplies the voice data to the second recording unit 14. The time generation unit 13 includes a crystal oscillator, for example, and supplies time data indicating the current time to the second recording unit 14.
[0023]
The second recording unit 14 has a detachable second recording medium, and records the image data from the camera unit 11 and the audio data from the microphone unit 12 on the second recording medium. The second recording unit 14 records image data or audio data, and records the time data from the time generation unit 13 as a time stamp (time data at the time of recording) on the second recording medium. .
[0024]
FIG. 5 shows an object recording time table recorded on the second recording medium by the image / sound recording apparatus 10 having such a configuration.
For example, Photo 1 was recorded at time “07:16:00”, Photo 2 was recorded at time “07:16:15”, Audio 1 was recorded at time “07:17:10”, and 3 was taken at “07:17:50”.
[0025]
FIG. 6 shows an image / audio output device 20 to which the present invention is applied.
[0026]
The image / audio output device 20 can be applied to a so-called personal computer. The image / sound output device 20 uses the trajectory data recorded on the first recording medium, the image and / or sound recorded on the second recording medium, the time data, etc. Correlate the voice with the position on the map.
[0027]
Specifically, the image / audio output device 20 displays a ROM 21 in which a control program is recorded, a CPU 22 that controls each circuit in accordance with the control program, a RAM 23 that temporarily stores data, a map, and the like. Monitor 24, a speaker 25 for outputting sound, a third recording medium 26 on which locus data is recorded, and a fourth recording medium on which image data and / or sound data and time data thereof are recorded. 27, a CD-ROM drive 28 that reads map data from a CD-ROM for displaying a map, and a communication circuit 29 that transmits and receives data to and from the outside.
[0028]
On the third recording medium 26, locus data similar to that of the first recording medium used in the locus recording apparatus 1 is recorded. That is, the third recording medium 26 may be the same as the first recording medium used in the trajectory recording apparatus 1. Further, the trajectory data may be recorded on the third recording medium 26 from the trajectory recording device 1 via a communication line such as the Internet or a communication circuit 29.
[0029]
The fourth recording medium 27 stores the same image data and / or audio data and time data as the second recording medium used in the image / audio recording apparatus 10. That is, the four recording media 27 may be the same as the second recording medium used in the image / audio recording apparatus 10. The fourth recording medium 27 may record the locus data from the locus recording device 1 via a communication line such as the Internet or a communication circuit 29.
[0030]
In the image / sound output device 20, as shown in FIG. 7, the CPU 22, based on the trajectory data recorded on the third recording medium 26, indicates the trajectory that the user has moved to A-B-C-D- It can be approximated by a broken line with E-.
[0031]
At this time, the CPU 22 reads time data indicating the time when the image data is recorded for the photograph 1 recorded on the fourth recording medium 27. The time data for Photo 1 is “07:16:00”. This time is the same as the time at point C. Therefore, the CPU 22 displays a map from the map data read from the CD-ROM drive 28 on the monitor 24 and displays an image of the photograph 1 on the monitor 24 in association with the point C.
[0032]
Thereby, since the image about the photograph 1 is displayed in association with the position on the map, the user can easily recognize the captured image and its position.
[0033]
Next, the CPU 22 reads out the image data and time data of the photograph 2 from the fourth recording medium 27.
The time data for Photo 2 is “07:16:15”. This time is intermediate between the time “07:16:00” at point C and “07:16:30” at point D.
[0034]
In this way, the CPU 22 considers that the user was moving at a constant speed during that time from the positions and times of the points C and D, complements the points C and D with a straight line, and calculates the midpoint between the CDs. This point is the position where the photograph 2 was taken. Thereby, as shown in FIG. 7, for example, the CPU 22 displays the image data of the photograph 2 and the intermediate point between the CDs on the monitor 24, for example, with the intermediate point between the CDs as the position where the photograph 2 is taken.
[0035]
The CPU 22 interpolates between the EFs before and after the time as shown in FIG. 7 for the voice 1 because the time is “07:17:10”, and divides it into 1: 2. The position where the voice 1 is recorded is calculated by performing weighting. Thereby, the CPU 22 clearly indicates the position where the sound 1 is recorded on the monitor 24 on the map and outputs the sound from the speaker 25.
[0036]
As described above, according to the image / audio output device 20 to which the present invention is applied, the trajectory data recorded in the image / audio recording device 10, the image and / or audio recorded in the image / audio output device 20, and With respect to time data, images and / or sounds can be output in association with each other.
[0037]
In the image / sound output device 20, when images and sound objects recorded by many image / sound recording devices 10 that do not have a position measuring mechanism are recorded only by comparing time stamps. Since the position of the object can be specified, the width of the device and the object that can utilize this can be greatly increased.
[0038]
Since the object whose recording position is specified is often associated with a map displayed on a personal computer or the like, a new information presentation scene can be provided to the user. At this time, the image / sound output device 20 can immediately place a large number of images taken by the image / sound recording device 10 on a map on the monitor 24.
[0039]
Furthermore, when a moving image is captured by the camera unit 11 in the image / sound recording apparatus 10, the image / sound output apparatus 20 displays the position on the map corresponding to the playback scene while moving the image during playback. You can also.
[0040]
Note that the processing in the image / audio output device 20 as described above may be performed by installing the control program in an information processing apparatus such as a personal computer from a recording medium on which a predetermined control program is recorded. .
[0041]
The present invention is not limited to the above-described embodiment, and for example, it is possible to make a design change as shown below.
[0042]
For example, in the present embodiment, the case where GPS is used for the positioning system has been described. However, the present invention is not limited to this, and the latitude and longitude may be measured by other methods.
[0043]
In addition, the latitude and longitude were measured for each point every 30 seconds. For example, after measuring the latitude and longitude for one point, for other points, only the difference between the latitude and longitude for the one point was measured. Alternatively, altitude may be recorded together.
[0044]
In the trajectory recording apparatus 1 described above, a large-capacity recording medium is required as the first recording medium if the interval between the recording times of latitude and longitude is shortened. On the other hand, if the recording time interval is increased, the first recording medium does not need to have a large capacity, but only a rough trajectory can be obtained. Therefore, if a vector composed of a speed and a direction is also used for recording, the amount of information can be efficiently compressed when there is no significant change in the moving speed or direction.
[0045]
In the present embodiment, the case where an image or sound is used as an object has been described as an example, but the present invention is not limited to this. That is, as objects, text data input from the keyboard, characters and pictures handwritten on the touch panel, predetermined control programs obtained through broadcasting and communication, various observation data recorded continuously or at points It is not particularly limited as long as it is associated with the position information.
[0046]
【The invention's effect】
As described above in detail, according to the recording medium on which the object output device, the object output method, and the object output control program according to the present invention are recorded, the position at the time indicated by the time information recorded on the second recording medium is determined. By calculating based on the trajectory data recorded on the first recording medium, displaying the calculated position, and outputting the object recorded on the second recording medium in association with the calculated position, Even when the trajectory data and the object are recorded separately, they can be easily associated with each other.
[0047]
In other words, a device that can determine the position later by simply checking the time stamp of an object recorded by many recording devices that do not have a position measurement mechanism, and can use this. The width of the object can be greatly expanded.
